Inflation

A Texan, a Greenhorn, and a Southern Belle are riding in a carriage through Texas. The Greenhorn says to the Southern Belle "I'll give you $10 for a blow job." At this, the Texan takes out his gun and shoots the greenhorn.

The Southern Belle, now a little flustered, fans herself and says "Thank you sir, for defending my honor." Then, the Texan gets a confused look on his face. "Your honor?! Hell! I was just trying to keep down inflation! Around here, a blow job costs $2!"
